Patent CA-2674939-A1 (CA)
Title: Liquid phase alkylation with multiple catalysts
Inventor: VINCENT MATTHEW J
IPC: C07C2/66
Filed: 2008-01-03
Abstract: A process is disclosed for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones, each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene are introduced into the first alkylation reaction zone. The first and second alkylation reaction zones are operated under conditions of temperature and pressure effective to cause alkylation of the aromatic compound with the alkene in the presence of the alkylation catalyst, the temperature and pressure being such that the aromatic compound is at least partly in the liquid phase. The alkylation catalyst in the first alkylation reaction zone, which may be a reactor guard bed, has more acid sites per unit volume of catalyst than the alkylation catalyst in the second reaction zone.

IPC: H04B1/7143
Filed: 2008-02-06
Abstract: Systems and methodologies are described that facilitate defining and utilizing hopping patterns to transmit broadband pilot signals in a wireless communications network. Portions of bandwidth can be dedicated to transmitting the broadband pilot data, and patterns can be utilized to hop across frequencies in given time periods to effectively utilize the entire dedicated bandwidth. Moreover, the periodicity for transmitting the data is configurable to allow devices requiring additional scheduling (e.g., high activity devices) to transmit the broadband pilot data more frequently. The hopping patterns can also hop across cyclic shifts of the patterns to provide optimum diversity for transmitting broadband pilot signals.

Title: System having one or more memory devices
Inventor: PYEON HONG BEOM
IPC: G11C7/10
Filed: 2008-02-19
Abstract: A system having serially connected memory devices in a ring topology organization to realize high speed performance. The memory devices have dynamically configurable data widths such that the system can operate with up to a maximum common number of active data pads to maximize performance, or to operate with a single active data pad to minimize power consumption. Therefore the system can include a mix of memory devices having different data widths. The memory devices are dynamically configurable through the issuance of a single command propagated serially through all the memory devices from the memory controller in a broadcast operation. Robust operation of the system is ensured by implementing a data output inhibit algorithm, which prevents valid data from being provided to the memory controller when read output control signal is received out of its proper sequence.

Abstract: Separation of hydrophobic particles from a mixture of particles in a fluid is performed by providing a fluidized bed (18) as a relatively non-turbulent contacting mechanism in a flotation cell incorporating a settling chamber (30) located immediately above the fluidized bed. Hydrophobic particles attach to bubbles in the fluidized bed 18 and rise to the interface (19) with the settling chamber (30) where non-hydrophobic particles (22) flow over the lip (20) of an internal launder and are removed as tailings at (21).  The hydrophobic particles attached to bubbles float upwardly in the relatively placid settling chamber (30) where unwanted gangue can fall back to interface (19). The bubbles form a froth layer at the upper surface of the settling chamber, and flow over the launder lip (32) carrying the hydrophobic particles. An operation of the apparatus is kept stable by recirulating fluid from the settling chamber (30) via pipe (40) and pump (41) to mix with new feed entering at duct (2).

Abstract: A railroad freight car brake beam with a strut having a pair of generally parallel and joined side walls disposed to opposite sides of an axis of the strut and having a central hollow portion along with a longitudinally elongated slot adapted to be inclined a predetermined number of degrees from vertical for accommodating an elongated brake lever extending through the strut. Each side wall of the strut defines a bore opening to the hollow center portion and to an exterior of the strut. The bores defined by the strut are aligned relative to each other to accommodate at least a length-wise portion of a brake lever pivot pin extending through the strut and serving to connect the brake lever to the strut. The aligned bores in the strut also define a pivot axis for the brake lever. The strut further includes a pair of bushings which journal the brake lever pivot pin. One bushing is accommodated in each bore de-fined by the strut. Cooperating instrumentalities inhibit inadvertent displacement of the brake pin bushings away from the axis of and relative to the strut thereby fixing the pivot axis of the brake lever relative to the strut.
